To all whom, it muy concern:

Beit known that I, FREDERICK Savane HEN- N1NG,inarine engineer, of the city of Toronto, county of York, Province of Ontario, Canada, have invented certain lnew and useful Improvements in Sectional Tater-Heaters, of which the following is a specification.

My invention relates to sectional waterheaters, more particularly as heated by gaseous or liquid fuel; and the object is to devise a simple compact form of furnace having water-sections and combustion-chambers so constructed as to promote circulation and having the heat applied in a more direct and economical method than at present in use; and it consists, substantially, in providing a plurality of similar interlocking water-sections provided with ingress-ports at lower levels, respectively, than the egress-ports and water-chambers circling spirally upward from the one to the other, a double water-post, cornbustion-chambers between the sections, having suitable burners placed therein and being connected by inclined conical vents, suitable Ventilating-doors and fuel-regulatin g devices being provided, as hereinafter more particularly described, and shown in the drawings hereunto attached, in which- Figure 1 is a sectional perspective view of a furnace made in accordance with my invention, partially broken away to show more particularly its construction. Fig. 2 is a vertical cross-section of the double water-post. Fig. 3 is a front detail of the Ventilatingdoors. Fig. 4: is a vertical section of the gasfeed pipe and air-injector.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is a sectional furnace having the similar sections B. The water-chamber b of the section B is made in the form of a spiral, circling from the ingress-port b at the rear upwardly around the whole of the section back to the egress-port b2, situated at a higher level at the rear, thus giving a continuous rise throughout each section from ingress to egress. The end walls h3 of the spiral water-chamber b are one over the other and are continued forwardly past the center, as the partition b4, to cause the water all to flow well to the front in pass-- ing around the chamber. The central parts b5 of the floor and b of the roof of each section are preferably made horizontal, as shown, the latter acting as a support for the burner C and the former, which is made as thin as possible, receiving the iialne from the burner below evenly throughout.

The peripheries of the sections B are provided with vertical flanges bl, the upper one having an external lip be, into which fits the lower flange of the section above. These flanges hold the water-sections well apart and afford room for the burners C, located between, thus forming separate combustioncharnbers between the several sections. A series of flues b9 are formed through each water-section, preferably larger at the bottom and contracted at the top, and all inclined in one direction, preferably toward the egressport and parallel with the periphery, thus giving the gases passing through a rotary velocity similar to that of the water and also preventing the current from a lower vent passing directly through the similar one above.

The water-post D has two vertical channels d and d', separated bythe partition d3. The channel d is closed at the top, but opens into the collecting-cap d4, bolted to the bottom, into which the return-pipes E lead. The channel d is closed at the bottom, but opens into the distributing-cap d5, bolted to the top, from which the flow-pipes E branch. These pipes lead throughout the house to be heated, are connected to radiators, and finally lead back to the furnace in the ordinary manner.

In the front of the channels d and d are ports d6 and C17, so placed that when the waterpost is bolted to the rear of the water-sections, the ports d6 and C17 come opposite the ingress and egress ports b' and h2, respectively, of each section.

Suitable water-tight packing is used wherever the water-joints are made.

A suitable escape-cock d8 is located at the foot of the water-post D to drain off the water when desired.

In front of the combustion-chambers are doors F, provided with adjustable darnpersf.`

The frame f' on which the doors are hung serves to bind the sections together in front, the water-post serving the same purpose at the rear.

On the top of the top section I preferably place a suitable cover G, having the gas-vent g leading therefrom, and at the bottom a suitable base H is provided.

The burner C may be of any form and adapted to the use of gas orliquid, or even of solid, fuel, or an electric heater might be used, the essential point of my invention being the application of heat directly and independently to each section.

Where gas is burned, I preferably use the ring-burners C, suitably supported so that the flame plays directly upon the thin at parts b of the bottoms of the sections B.

The supply-pipes chave shoulders c', abuting bosses b9, formed on the peripheral iianges bl of the sections B, and projecting through 1 are screwed into air-injecting cups C2, having ordinary circular dampers c2.

The external vertical gas-pipe C3 has ordinary gas-cocks c3, supplied with suitable nozzles c4, which project through the dampers c2 in the form of injectors, as shown in Fig. 4.

The gas may be regulated for each burner separately or may be regulated for all by the main cock c5. I preferably also provide the supplemental cock c, which is operated from any desirable part of the house by the rod c7, the farther end of which is supplied Wi th an index-point c8 and handle o9, and preferably the adjustable rings cm, which limit the rods movement by contact with the intermediate support-ing-ring C11. The rings C10 may be so adj usted that on placing the index-point opposite certain indicating-marks the heat may be regulated 4from full on or low, or even turned out, if necessary.

For igniting the burners I attach to the gaspipe the flexible gas-tube J, provided with a suitable cocky', and elongated nozzle j,which may be inserted through the door, as shown in Fig. 1.

By my invention a furnace is provided in which the heat is independently supplied to the water in each section, and the water as it is heated rises in each section naturally to the egress-port on account of the upward inclination of the section. This facilitates the iiow very greatly, particularly on starting and when very little heat is required, as during the spring and fall. Great economy of fuel is effected by the ready regulation of the combustion to the heating required. The heat may be applied to one or more sections, as required, the water from the heated sections alone circulating through the pipes, that in the other sections lying more or less dormant. Cleanliness and ease of management are points in favor of my furnace, which may be placed in any convenient part of the house, such as the corner of a kitchen or hall.
